Rigrodsky & Long, P.A. announces that it is investigating potential legal claims against the board of directors of MOD-PAC Corp. ("MOD-PAC" or the "Company") (NASDAQ GM: MPAC) regarding possible breaches of fiduciary duties and other violations of law related to the Company's entry into an agreement to be acquired by a group consisting of the Company's President and Chief Executive Officer, Daniel G. Keane, and its Chairman of the Board, Kevin T. Keane, and their affiliates and associates (the "Buyer Group").

Under the terms of the agreement, the Company's shareholders, excluding the Buyer Group, will receive $8.40 per share in cash for each share of MOD-PAC they own.
